A piece I wrote last year about native mussel species of the Tennessee River watershed is out now in the Summer issue of the Oxford American. I am delighted to see it in print, and I could not have asked for a better photographic pairing: Sally Gall’s “Efflorescence.”

The OA doesn’t post all content of current issues, so you’ll have to go to the newsstand and pick up a copy, or get a subscription—it’s a spectacular magazine. (Also in this issue, Wyatt Williams follows John McPhee to Florida, after Oranges.)

Thank you for reading.
